Experience
Frontend Application Developer at Stockxbid Technologies Private Limited (2024-02 – Present)
- Shipped 2 production React Native apps (Buyer + Seller) for Outxtock to Google Play Store, and the Outxtock React.js web platform – sole frontend engineer across all three surfaces.
- Reduced app and web load time by ˜40% via lazy loading, code splitting, memoization (React.memo, useMemo, useCallback), and Redux Toolkit refactoring.
- Optimised React Native FlatList (keyExtractor, getItemLayout, removeClippedSubviews) – eliminated scroll jank and reduced memory overhead by 50%.
- Improved Lighthouse scores by 28 points by diagnosing root-cause issues (memory leaks, layout thrashing, unnecessary re-renders) via Chrome DevTools and Flipper – not surface patches.
- Built and owned automated test suite (Vitest + Playwright) for Anustaan – catching critical bugs pre-release and eliminating regression reliance on manual QA.
- Architected end-to-end Zod validation across onboarding flows, eliminating a class of runtime data errors that previously reached production.
- Owned 8 production features end-to-end (wireframe to deployment) collaborating with product and backend teams; integrated REST APIs with Redux Toolkit state management – API failures reduced to near zero in production.
